摘要: The interaction of an E/A = 70-MeV Be-7 beam with a Be target was used to populate levels in Be-6 following neutron knockout reactions. three-body decay the ground and first excited states into alpha + p exit channel were detected High Resolution Array. Precise correlations extracted from experimental data allowed us obtain insight mechanism democratic decay. correlation are good agreement three-cluster-model calculation thus validate this theoretical approach over broad energy range.
